Ok here is the deal ive got a buddy's 60gb ipod video (fat one) and he is relly on a budget. Question is: can i replace the currently busted 60gb hard drive with a 30gb one? He just uses 15gb 20 tops so i figured why pay for the 60 gb when the 30gb is half the price. Will it work? Will the 60gb ipod video accept the 30gb hard drive? Thanks!
